JAVA_HOME is not defined correctly.
-
I'm using Ubuntu 12.04 and I installed ant with
@apt-get -u install ant@
When I try to run my app in the android emulator I get this output:@20:59:48: The process "/usr/bin/make" exited normally.
20:59:48: Copy Qt app & libs to Android package ...
20:59:49: Creating package file ...
20:59:49: Package deploy: Running command '/usr/bin/ant clean debug'.
Error: JAVA_HOME is not defined correctly.

Error while building/deploying project Test (kit: Android for arm (GCC 4.6, Qt 5.1.1))
When executing step 'Packaging for Android'
20:59:49: Elapsed time: 00:05.@I read it's a java problem. I'm not an expert but, if the problem is Java, why I can run correctly java software (Eclipse)?

Hi and welcome to devnet,
Disclaimer: I'm not yet proficient in Qt Android build
Did you check the value of JAVA_HOME in your Build Settings ?
-
Thanks :)
I search around and I try to execute ant form terminal and then I read that my JAVA_HOME was not set.So I installed JDK with
@sudo apt-get install openjdk-6-jre@then I set
@export JAVA_HOME="/usr/lib/jvm/java-6-openjdk-amd64;"@and now I have an ant problem:
@ant
Buildfile: build.xml does not exist!
Build failed@and when I try from Qt-Creator to run my project I get
@Error while building/deploying project Test (kit: Android for arm (GCC 4.6, Qt 5.1.1))
When executing step 'Deploy to Android device'@
-
You should not have a semi-colon in your JAVA_HOME path.
Did you set it globally ? i.g. in your .profile file ?
If not, it won't be available to program run outside the console where you set it.
-
I'm sorry, what and where I have to write....
I hate java but I used it for 4 months for university in an other ubuntu installation without any of these problems...
-
Since you just installed it, you could try to just logout/login to check wether your environment has been properly updated.
-
I removed java 6, reinstalled java 7 and then logout/login
I retry and I get
@23:26:32: The process "/usr/bin/make" exited normally.
23:26:32: Copy Qt app & libs to Android package ...
23:26:33: Creating package file ...

Packaging Error: Command '/usr/bin/ant clean debug' failed.Exit code: 1
Error while building/deploying project Test (kit: Android for arm (GCC 4.6, Qt 5.1.1))
When executing step 'Packaging for Android'@So I have to set JAVA_HOME.
Now, I have to add:@export JAVA_HOME=/usr/lib/jvm/SOMETHING@
But something what? I post the content of /usr/lib/Jvm
@default-java java-1.7.0-openjdk-amd64 java-6-openjdk-common
java-1.6.0-openjdk java-6-openjdk java-7-openjdk-amd64
java-1.6.0-openjdk-amd64 java-6-openjdk-amd64 java-7-openjdk-common
@and then, I have to add the line in which file? .bashrc? .profile?
Thank you for the help....
-
Did you check the JDK location in Options -> Android from QtCreator ?
-
It's set to /etc/java-7-openjdk but there are not a bin folder in it and that's probably why I get
@Error: JAVA_HOME is not defined correctly.
We cannot execute /etc/java-7-openjdk/bin/java@So is that what I have to change? Change in what?
-
Change it to point to the folder where you have your java executable installed
-
Now the problem is elsewhere

-
Maybe I should remove and reinstall java and all the components that I need to compile for android...
-
Where is javac to be found ?
-
Can you post what you get when you fire "which java" command from the terminal ?
-
Ok, so:
@$ which java
/usr/bin/java
@
-
If I retry from QtCreator, from Compile Output everything seems ok but I get:
Application Output
@Starting remote process.Unable to start 'org.qtproject.example.Test'.@
-
i think you also need to install the jdk.
Try @apt-get install openjdk-6-jdk@
-
Yep it's installed:
@sudo apt-get install openjdk-6-jdk
[sudo] password for andrea:

Try setting JAVA_HOME to "/usr/lib/jvm/java-6-openjdk-amd64/bin"
As it contains both javac and java (symbolic link to ../jre/bin/java )
-
Ok so I have to add
@export JAVA_HOME="/usr/lib/jvm/java-6-openjdk-amd64/bin"@but where? in .profile? .bashrc?
Thanks
-
Yup. try in bashrc or /etc/environment
-
Done. Now if I run...
"Application Output":http://pastebin.com/eqJCfW9p
"Compile Output":http://pastebin.com/bGSZmun5
I think it's not a Java problem anymore...
-
I'm not understanding anything.
Last update, every time I click on "run" I get
Application Output:
@Starting remote process.Unable to start 'org.qtproject.example.Test'.@and General Messages
@Could not read qmake configuration file /home/andrea/Qt5.1.1/5.1.1/android_armv7/mkspecs/android-g++/qmake.conf.@Maybe this is the problem now, I've never checked this tab before...
-
Well from the compile output it seems that the APK has been created
@/home/andrea/Code/QML/Test/android/bin/Test-debug.apk@
But on deployment to the emulator it crashes due to some OpenGL issues.
I donot have much detailed idea about this.
But just try to deploy this APK on a physical device and see if it works.
-
I tried in a physical device and it works!!!!!!!
But I can't reupload the apk every time to check if it's working well....so maybe I should open a new topic for this issue, what do you think?
Thanks a lot for the help!
-
Yes. You can try asking in new post with appropriate details
-
I've done it, thanks all for the help

I also struggled with the "Buildfile: build.xml does not exist!". It was because I only installed openjdk-7-jre. openjdk-7-jdk is also required.
Qt Creator kept saying "/usr/lib/jvm/java-7-openjdk-i386" was invalid for the JDK location. I guess it looks for something that openjdk-7-jdk puts in the /usr/lib/jvm/java-7-openjdk-i386. After installing openjdk-7-jdk, Qt Creator was happy with the location.
(Using Kubuntu 14.04, JAVA_HOME set in /etc/enviroment)
